Zhang Hui (L) and Sun Lina, both technicians with the Yungang Grottoes Research Institute, restore paintings in their studio in Datong, north China's Shanxi Province, on May 8, 2021. Listed as a UNESCO World Heritage site in 2001, the Yungang Grottoes is a 1,500-year-old Buddhist site that contains more than 51,000 statues of the Buddha, with the largest measuring 17 meters high and the smallest two centimeters. The Yungang Grottoes Research Institute, for its part, boasts a relics protection and restoration team mainly composed of professionals in their 20s and 30s, who are trying their very best to keep these statues in their prime condition as long as possible. Armed with modern technologies, these young people have gone beyond fundamental protection and restoration, and walked the extra mile to present these statues in a much more vivid way before tourists and learners from all over the world.
